Hi Dris... Maybe this can give you a wee bit of hope... just after my daughter, through scrimping and scraping , managed to buy her first flat a family of down and outs moved upstairs to her. There were 5 children of varying ages, a mum on drugs and on the 'game' also several dogs. The kids were out of control and men were hammering on the doors at all times of the day and night. My daughter put her flat on the market and although it took a while she sold it to a renting agency. She now has a nice little house which she loves. She has been through the mill what with the flat, poor health and an ex husband who walked out just before Christmas. She's now absolutely fine.
I hope all turns out the same for your daughter - I know only too well what it feels like to be worried sick about a child no matter how old they are.
My love and thoughts go out to you both xx
